I quickly looked at your home page. I see many interesting features mentioned, but it didn't come clear to me who is your target customer, what problem you're solving, and what benefit you're providing. In other words, the value proposition of your offering is not clear.
That may give a clue as to why you're struggling for traction in the market. I see features, technology, something about a loyalty club, even something about an affiliate program, but nothing that comes out clear as day that says "Hey customer X, you have problem Y, and we have a solution that will give you benefit Z that you so desperately want."
You need to get it down to a value prop as clear as that. That's the hook that will get your customer interested in then understanding the "how" part of your solution.
There are some excellent suggestions already made here by others as to how you can do this. Chief among them I endorse the idea of talking with your existing customers about why they bought your product and the benefits they're gaining, and then to prospective customers you didn't win over to find out why they didn't buy your service. Use that to interview other target customers to validate the problem you're trying to solve, see if it resonates, if there's a real market opportunity out there.
Based on that, you can determine whether it's simply modifying your messaging, or you're faced with a problem pivot, a customer pivot, or a solution pivot. Best of luck!
